JEEP TJ FRAME BACK HALF KIT
SKU MB3008



The Motobilt Jeep TJ back half kit is the most complete on the market. This kit replaces the back section of frame rails to allow space to clear coilover shocks and increase departure angle. How does the the Jeep TJ back half kit do this? The Motobilt kit moves the frame rails from inside the wheel opening to the bottom side of the tube. In doing so the bumper location is moved up to just below the tailgate. This kit requires an experienced welder/fabricator to install.

Building custom four link suspension on a Jeep TJ does not have to be difficult. The Motobilt Jeep TJ back half kit is an effective way to gain clearance for suspension components like coilovers shocks, bypass shocks, or ORI struts. The Jeep TJ Back Half Kit moves the frame rails to the bottom side of the tube. The frame rails will mount directly to the bottom side of the rear floor board for a tight compact fit. It should be noted the kit requires cutting sheet metal on the body just below the tailgate to allow the frame rails to extend out. The bumper is then attached in this new location. The Motobilt kit comes complete with a rear bumper.

What does the Motobilt Jeep TJ back half kit include? The kit includes 7 parts total in the shipment. Two lower frame rails sections and two upper frame rail sections. The installer will joint the upper and lower sections together during the mock up stage of the installation. The fifth part is the rear bumper assembly. The rear bumper comes complete with 3/4 inch thick d-ring mounts. The kit also comes with two end caps for the bumper and frame. These are welded in place to attach the rear bumper.

All of the parts of this kit other than the d-ring mounts are fabricated from 3/16 inch high strength steel plate and formed on a press brake. Unlike some of the other kits on the market we do not require you to purchase square tubing to complete the project. With that said we provide a flat point on the back center of the rear bumper for the installer to triangulate some round tubing if required. The 3/4 inch thick high strength steel plate d-ring mounts pass all the way through the rear bumper and weld in place on both sides for ultimate strength. The d-rings have a 1 inch hole in them.

JEEP YJ BACK HALF KIT
SKU MB3001


The Motobilt Jeep YJ Back Half Kit is designed with function in mind. We may not be the cheapest but we certainly offer the best product on the market with years of experience to back up the product design. Motobilt is defined by high quality parts and design. The Motobilt Jeep YJ Back Half Kit was designed to meet a few different needs. The journey started about 15 years ago when Dan DuBose back halved his Jeep YJ to make more room for shocks and to gain ground clearance in the rear. Over the years the hand made design evolved into laser cut and formed parts. The design has been refined with specific goals in mind.

The Motobilt Jeep YJ Back Half Kit was 3D CAD designed in Solidworks for a precision fit. The parts are then CNC laser cut from 3/16 inch thick flat steel plate, formed on a press brake, and then welded. This design and fabrication approach allows us to do things that simple box tube parts can not. The rear bumper is integrated into the design. The bumper features a very tight fitting profile with 3/4 inch thick d-ring mounts.

Why installed the Motobilt Back Half Kit on your Jeep YJ? This kit provides room to mount coilover shocks and not hit the frame rails. We moved the frame rails from the factory location in the rear wheel well to under the rear floor board. This allows plenty of room to get your coilover shock angles set up correctly. Another reason is to gain about 7 inches of ground clearance in the rear bumper area.

This part requires extensive cutting and welding. It is recommend to have someone experienced installed this kit. It will require cutting the frame in half, cutting the body below the tailgate to allow the new frame to pass through, and welding the parts in place. Motobilt also recommends connecting your roll cage to the frame rails for added support. This kit will also require you install a fuel cell. The factory gas tank will not work with this kit.
